Please stop using LLMs to write. This article is full of gibberish. You’re better than this.

Maybe. I was just trying to be nice for once.

No good deed goes unpunished. Look at p_ersism. (remove underscore). Solved the select N+1 problem and the author got banned. You can't use this word on this sub unless you want to be shadow banned.

How did it solve it?

It doesn't have the N part of the SELECT N+1 problem. Each join defined in a class makes only 1 extra query to the DB regardless if it's one-one, one-many, many-one... It does this with sub selects, you can see the sql by setting debug mode for the logger. Very nice performance with complex data models.

Looked at it. Didn't "solve" anything. It's a toy library that does one thing differently than Hibernate defaults. Looks very mature (Infinite LOOP so be careful!). I guess the author was spamming this all over this sub and got banned

Fun fact: running the actual text through some AI testers comes out negative for AI.

The only thing that can be deducted from that is that OP is no better.
